<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua",serif">I’ve check out these patches and see if they fix the problem before I consider filing a bug.

<p>Hi again,<o:p></o:p></p>
<p>What version of the compiler are you using? I'm wondering if this was fixed by r311041+r311043.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:36.0pt">That's pretty odd. Can you rule out for sure that the files aren't being written somewhere unexpected or that the other clang was built against different sources?<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif"">Yes you’re right, it appears to be in ‘</span><span style="font-size:12.0pt;font-family:"Courier New"">c:\tmp\foo-XXXXXX.opt.yaml</span><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif"">’,
though on Linux it is located in ‘</span><span style="font-size:12.0pt;font-family:"Courier New"">./foo.opt.yaml</span><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif"">’. The sources for my Linux and VS2015 builds are identical.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif""> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Book Antiqua \,serif"">So it would appear that the temporary files is being created but not finalised – probably a CLang driver issue. I’ll dig deeper and see where this is going wrong and I’ll
re-post this to CFE-Dev.</span><o:p></o:p></p>

Sounds like a bug (I've never tested on Windows). I suggest filing a bug report. Also, in general, you'll have better luck with frontend questions on cfe-dev.<br>
